Study information

Scientific title

Condition

Mild allergic asthma

Intervention

Investigational and control drugs:
Investigational: MEM 1414 tablets, 100 mg (6 tablets per day for a total of 600 mg), will be administered orally once daily for 7 consecutive days
Reference therapy (control): matching placebo tablets (6 tablets to conserve the blind) will be administered orally once daily for 7 consecutive days

Treatment arms:
Subjects will be assigned to each of the following treatments in a randomised order, each separated by a washout period of approximately 2 - 10 weeks (washout period 2):
1. 600 mg MEM 1414 once daily for 7 consecutive days (six 100 mg tablets)
2. Placebo once daily for 7 consecutive days (six placebo tablets)

Treatment assignment:
Subjects will be randomised in a 1:1 ratio to the two possible sequences of treatments:
1. MEM 1414 in treatment period A, placebo in treatment period B
2. Placebo in treatment period A, MEM 1414 in treatment period B

Subjects will be followed up 5 - 10 days after the last study drug administration.

MEM 1414

Primary outcome measures

To assess the efficacy of MEM 1414 compared to placebo on the late asthmatic response (LAR) following an inhaled allergen challenge, as measured by changes in FEV1 compared to baseline. The LAR is defined as a fall in FEV1 of greater than 15% from baseline between 3 - 10 hours at least once following inhalation of house dust mite (HDM) extract.

Secondary outcome measures

1. Assess the efficacy of MEM 1414 compared to placebo on the late asthmatic response following an inhaled allergen challenge, as measured by:
1.1. Changes in allergen-induced airway hyperresponsiveness (via pre- versus 24-hour post-allergen challenge PC20 methacholine values)
1.2. Changes in the following biomarkers of allergen-induced airway inflammation compared to baseline:
1.2.1. Exhaled nitric oxide (eNO)
1.2.2. Whole blood tumour necrotising factor alpha (TNF-alpha), interleukin-6 (IL-6) and leukotriene B4 (LTB4) concentrations
2. To investigate the safety and tolerability of MEM 1414 compared to placebo in steroid-free subjects with mild allergic asthma
3. To characterise the pharmacokinetic profile of MEM 1414 in steroid-free subjects with mild allergic asthma

Eligibility

Participant inclusion criteria

1. Male or female subjects between the ages of 18 and 55 years (inclusive)
2. Non- or ex-smokers who are expected to not smoke for the duration of the trial (an ex-smoker being defined as someone with less than 10 pack-year history and who has completely stopped smoking for at least 12 months before screening for this study)
3. Clinically stable, steroid-free mild allergic asthmatics who:
3.1. Have had a well-established, documented asthma diagnosis for at least 6 months prior to screening for this study
3.2. Have a forced expiratory volume in one second (FEV1) greater than or equal to 70% of predicted for age and height on screening days 1 and 2
3.3. Do not require any controller drugs for asthma
3.4. Have been on an as needed regimen of short acting beta 2-agonists
4. In the previous year or at screening, a positive allergen skin prick test (SPT) wheal response to house dust mite (HDM)
5. At screening, a demonstrated airway hyper-responsiveness to methacholine chloride, with a provocative concentration resulting in a 20% decrease in FEV1 (PC20FEV1) of 16 mg/mL or less (a PC20 methacholine value within the previous 12 months may be used to make this determination)
6. At screening, a minimum decrease in FEV1 in both early (0 - 3 hours) and late (3 - 10 hours) allergen-induced response of greater than or equal to 15% following inhaled allergen challenge
7. Due to unknown risks and potential harm to the unborn foetus, sexually active women of childbearing potential must use a reliable method of birth control while participating in this study and for a period of 90 days following the last drug administration. Reliable methods of birth control are considered to be: abstinence (not having sex), oral contraceptives (the "pill"), intrauterine device (IUD), Depo-Provera, Norplant, tubal ligation ("tubes tied"), or vasectomy of the partner (with confirmed negative sperm counts) in a monogamous relationship (same partner). An acceptable, although less reliable method involves the careful use of condoms and spermicidal foam or gel and/or a cervical cap or sponge. Females who do not use an acceptable contraceptive regimen will be allowed to participate in this study only if they are not considered to be of childbearing potential: females who have had a hysterectomy or tubal ligation, are clinically diagnosed infertile, or are in a menopausal state (minimum of a year without menses).
8. Pregnant women are excluded from participation in this study. Because some methods of birth control are not 100% reliable, a negative pregnancy test is required at screening.
9. Male subjects must abstain from unprotected sexual intercourse during the study and for a period of 90 days following the last drug administration
10. Are in good general health and are expected by the investigator to complete the clinical trial as designed
11. Have voluntarily provided informed consent and have signed an informed consent form (ICF) indicating that the purpose of the study has been explained, and are willing and able to adhere to the study regimen and study procedures described in the ICF
